| Abstract: | According to the research development on the ordinary test methods of residual stress, it was pointed out that the more suitable test methods were blind-hole and X-ray method. But the blind-hole drilling method may hurt specimen, X-ray method request strict test environ- ment, and the other test methods can＇t fulfill industrial demand on effectiveness, accuracy and operation convenience. The residual stress measuring based on indentation has been considered noteworthy. The indentation response is related to residual stress existing in components. So the values from indentation response are in good agreement with that from the blind-hole method, meanwhile specimen hurt may be avoi- ded, the residual stress measuring technology based on indentation response will definitely display its engineering application prospects. |
